A "one in, one out" deal agreed by the UK and French governments on Thursday proposes that for each migrant the UK returns, Britain will accept another who has made a legal claim in France.

Britain will grant asylum to one migrant in France who can prove a family connection to the U.K. in exchange for each arriving migrant taken back by France.

The UK and France have agreed to a ‘one in, one out’ migrant deal that will see failed asylum seekers returned to France for the first time since Brexit.
